Document 1: Memo from Apple Orchard Owners to Employees

Document 2: Pump Placement Proposal from Employee A

Document 3: Pump Placement Proposal from Employee B

Consider each of the following statements. Does the information in the three sources support the inference as stated?

Yes

No

Yes

No

If Employee A’s program had been implemented, using consecutive two digit pairs of numbers to represent individual plots, the total number of bushels produced on those 10 plots, when multiplied by 10, would underestimate the total productivity of the entire field.

Yes

No

Since Employee A is using computer generated randomized digits, his plan will be successful in representing the entire field since there is no human bias in the selection, unlike Employee B.

Yes

No

If Employee B had suggested all ten plots at the west (left) end of the field, his computations for productivity would have been roughly the same (within a 5% error) as the computation resulting from his suggestion about using all ten plots on the east (right) end of the field.

Yes

No

If Employee B had decided to simply choose one plot from every east-west row, independent of the other rows, and if Employee A had chosen 10 plots at random from anywhere in the field, then the lowest and highest possible estimates from Employee B would differ by less than the lowest and highest possible estimates from Employee A.
